6. Distortion

The Fujinon lenses designed for the X system don’t correct the distortion at all, leaving that task to a camera’s software. However a company like Zeiss, renowned for its good quality optics, should try to construct optical instruments which correct basic optical aberrations in a proper way. After all the distortion correction done by a camera’s software comes with a price and we’ve written about it several times. The Zeiss optics constructors let us down a bit here because, in our view, they took the easy way out. The distortion measured in RAW files amounts to –1.88% which means that they didn’t really try to correct it properly. Overall that level is perhaps not especially high but we find that result hardly impressing for a standard lens, with an angle of view of less than 50 degrees,. What’s interesting, the camera body, used in the test, doesn’t show the proper lens distortion value, overcorrecting it noticeably. The distortion measured in JPEG files has a different sign and amounts to +0.57%. The performance of the Zeiss in this category surprises us especially as the rival Fujinon 1.4/35 corrected the distortion well; even in the RAW files it was just –0.55%.
